Description
Technical field
The utility model belongs to charcoal element production unit, adds before cakingagent kneading the heating unit that siccative is rapidly heated especially for the moulding of Carbon Anode Products green compact.
Background technology
Kneading and compacting is the second operation work that Carbon Anode Products is produced, and meet sufacing size and the volume density specification of quality of raw product moulding, and desirable mixture quality is that good thickener plasticity is the key of green compact quality-guarantee.At present, the practical situation of domestic kneading and compacting of the same trade are: the temperature difference of two kinds of materials that enters kneading pot is larger, and cakingagent coal-tar pitch temperature is high, and siccative temperature is low, makes mixture quality poor.Its technological process is, press the siccative that technical recipe forms, deposit in without any intensification and add in the hopper of thermal medium, by the current relatively upper strata pot of advanced double-deck kneading pot, be dry mixed, by thermal oil, carry out siccative intensification, time is 40-45 minutes, and material temperature rises to 105-110 ℃ by normal temperature laboratory, and the oil temperature of cakingagent modified pitch used is 175-180 ℃.Now, the siccative temperature that enters kneading pot is lower 70 ℃ than the temperature of cakingagent, and the temperature difference of two kinds of materials is that current thickener is invaded profit, the poor ubiquitous technical barrier of mixture quality.
Utility model content
In order to overcome existing double-deck kneading pot siccative, heat up slow, the still deficiency that affects mixture quality on the low side of the rear siccative temperature that heats up, the purpose of this utility model is to provide a kind of Carbon Anode Products siccative heating unit that is rapidly heated, this Carbon Anode Products siccative heating unit that is rapidly heated can be fast heated to 177-180 ℃ of optimum matching that reach with 175-180 ℃ of cakingagents by siccative from room temperature, fundamentally solves goods thickener difficulty and invades profit, the poor ubiquitous technical barrier of the current domestic same industry of mixture quality.
The utility model solves the technical scheme that its technical problem adopts: a kind of Carbon Anode Products siccative heating unit that is rapidly heated, it is characterized in that: on housing top cover, opening for feed is housed, bottom is provided with discharge port, in housing, be spaced at least 5 layers of coiled wear-resistant thermal oil coil pipe, thermal oil coil pipe lower end is connecting the heat conductive oil inlet that is positioned at lower housing portion, upper end is connecting the thermal oil outlet that is positioned at housing top, and heat conductive oil inlet is provided with the magnetic valve of controlling thermal oil flow according to required material temperature.
Described housing is formed by connecting by columniform shell upper and conical outer casing underpart, and housing is sandwich structure, is filled with oil resistant, fire-retardant lagging material in interlayer.
Spacing between described snakelike thermal oil coil pipe adjacent two layers is 15-30cm.
Gordian technique of the present utility model is, after the top of material dosing bin is ripe broken screening, after calcined coke screening and after abrasive dust, three places newly increase three and take the heating unit that is rapidly heated that thermal oil (temperature 210--230 ℃) is medium, siccative was warmed up to after 177-180 ℃ in 5-7 minutes, enters the material dosing bin by thermal oil (temperature is the same) insulation.By technical recipe, enter kneading pot, siccative temperature now reaches the optimum matching with 175-180 ℃ of cakingagents, has fundamentally solved goods thickener difficulty and has invaded profit, the poor ubiquitous technical barrier of the current domestic same industry of mixture quality.For producing high quality carbon anode green compact, provide reliable process technical guarantee.
The beneficial effects of the utility model are:
1, being dry mixed work efficiency obviously improves: the object that material is dry mixed improves siccative temperature exactly, the successful research and development of this invention have effectively been shortened the time of being dry mixed, siccative is developed by new invention before entering material dosing bin be rapidly heated heating unit by siccative temperature increase to and the optimum temps that matches of cakingagent temperature, compare with former technique, obviously shortened the time of being dry mixed, originally every pot shortens to 5-7 minutes in 40-45 minutes, improves 7-8 times of work efficiency.
2, being dry mixed quality obviously improves: owing to being dry mixed the shortening of time, by the requirement of technical matters formula, each grade purity is basicly stable.Former technique is long because being dry mixed the time, and particulate material is macrobead material badly broken particularly, causes the fluctuation of material level purity larger, and application of the present invention has thoroughly made up defect and the deficiency of former technique, makes material stable uniform more.
3, green compact quality obviously improves: former technique because of two kinds of material temperature difference of kneading large, cakingagent coal-tar pitch is poor to the wettability of siccative, thickener plasticity is poor, the phenomenon ubiquity that moulding difficulty is shaken, the common method solving is to extend time of vibration, normal monolithic needs 200-260 seconds, and the prolongation of time of vibration hides some dangers for to green compact internal soundness defect.The thickener vibratory compaction time shorten of output of the present invention is within 100-120 seconds, to improve work efficiency 50%.This technical indicator is that current domestic carbon anode is produced optimum technology parameter.Meanwhile, green compact surface size and internal soundness are more reliable and more stable.
4, energy-saving effect is obvious.Be dry mixed the shortening of time, compound economize on electricity 4.5 degree per ton.Liao ︰ oil=84.5 ︰ 15.5 of Aning calculates, and in thickener per ton, siccative economize on electricity is 4.5 degree * 84.5%=3.8 degree electricity; The shortening of time of vibration, moulding green compact economize on electricity 2.1 degree per ton.Add up to green compact economize on electricity 3.8+2.1=5.9 degree per ton.By 340,000 tons of green compact of company's annual capacity, calculate year economize on electricity 200.6 ten thousand degree.162.5 ten thousand yuan of energy-saving benefits.
5, carbon anode final product quality obviously improves: the raising of green compact quality is mainly reflected in the raising of green compact degree of compactness, and volume density, by former technique 1.45g/cm3, is brought up to 1.65g/cm3, and the main physical and chemical index of carbon anode finished product is significantly improved.Wherein: 2-3 of resistivity decreaseds, drop to below 55 by 57; Compressive strength improves 4-5, by 36, brings up to more than 40; Volume density is brought up to more than 1.57 by 1.54; Air permeability drops to below 2.0 by 2.5; Oxidation-resistance remaining (carbon dioxide reaction, air reactive) increases by 3-4%, reaches more than 90%.Above physical and chemical index all reaches the quality standard of domestic, international two large market high quality carbon anodes at present.
